That's... I don't know how to qualify this article, but it's just doesn't quite work that way. The semantics of redirection are same on Windows as on Linux. net user username /DOMAIN > /dev/null 2>&1 or, under native shell (cmd) net user username /DOMAIN > nul: 2>&1 > I tried file descriptor 3, but that resulted in an error regarding > unsupported file handle,. or something like that. > I was considering using IPC::Run3, but I don't think that will help > with suppressing error message and usage message. > Perhaps there is a Perl module that is native to Cygwin that will > perform this kind of lookup for me?

Another solution is to assign your own handles to the underlying process, but considering you don't want the output at all, I don't see it viable. -- With best regards, Andrey Repin Saturday, January 23, 2016 15:42:00 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
